STRUCTURES FOR AUTOMATED, MULTI-STAGE PROCESSING OF NANOFLUIDIC CHIPS
Techniques regarding one or more structures that can facilitate automated, multi-stage processing of one or more nanofluidic chips are provided. For example, one or more embodiments described herein can comprise a system, which can comprise a roller positioned adjacent to a microfluidic card comprising a plurality of fluid reservoirs in fluid communication with a plurality of nanofluidic chips. An arrangement of the plurality of nanofluidic chips on the microfluidic card can defines a processing sequence driven by a translocation of the roller across the microfluidic card.
Disposable Flow Through Diagnostic Device and Method of Construction Thereof
A disposable diagnostic device includes a body having a first channel and a second channel spaced from the first channel. A shroud is operably fixed to the body and encloses a chamber which is configured in a hermetically sealed-off relation from the first and second channels when the device is in a non-activated first state and is in open communication with at least one of the first and second channels when the device is in an activated second state. A reactant and an inert gas are disposed in the chamber such that the inert gas protects the reactant from being exposed to contaminants when the device is in said non-activated first state. A method of constructing a disposable diagnostic device is also disclosed.
Multi-well sample testing apparatus and methods of sample testing using the same
A sample testing apparatus includes a sample tray defining a planar surface and a plurality of wells recessed relative to the planar surface, and a lid member configured to be sealed about the planar surface of the sample tray. The lid member includes an adhesive layer configured to be sealed to the planar surface of the sample tray, a breathable film layer disposed about the adhesive layer, and a backing layer disposed about the breathable film layer. Methods of using the sample testing apparatus for testing a sample and kits to facilitate such testing are also provided.
Modular fluid chip and fluid flow system comprising same
A modular fluid chip according to an embodiment of the present disclosure includes a body including at least one first hole which allows fluid to flow therethrough; and a housing receiving the body therein, and including a second hole which corresponds to the at least one first hole and allows the fluid to flow therethrough, and a fluid connection part which is connectable to another modular fluid chip.
Device for whole blood separation
Separation of the cellular components of whole blood, or other biological fluid, from plasma or serum can be achieved for assay analysis. A device for facilitating separation can include, for example, a capillary tube that accurately draws target blood volume, a pad that chemically interacts with red-blood cells, such that the red blood cells become chemically and/or physically trapped within pad material, a mechanism for plasma recovery from the pad upon diffusion or active mixing, and a dropper tip that facilitates dispensing the mixture onto a test device. The treatment of the cellular components can be performed prior to contact with a buffer solution, so release of the cellular components into the buffer solution is reduced or prevented. Additional filtration can be provided to filter any remaining cellular components in the mixture.
Sample manipulation and assay with rapid temperature change
Among other things, the present invention is related to devices and methods of performing biological and chemical assays, particularly an easy sample manipulation and/or a rapid change or a rapid thermal cycling of a sample temperature is needed (e.g. Polymerase Chain Reaction (PCR) for amplifying nucleic acids).
PHARMACEUTICAL CONTAINERS INCLUDING SEALING ASSEMBLY WITH FILLER MATERIAL
A sealed pharmaceutical container including: a shoulder; a neck extending from the shoulder; a flange extending from the neck, the flange including: an underside surface extending from the neck; an outer surface extending from the underside surface, the outer surface defining an outer diameter of the flange; and an upper sealing surface extending between the outer surface and an inner surface defining an opening in the sealed pharmaceutical container, and a sealing assembly including: a stopper including a sealing portion extending over the upper sealing surface of the flange and covering the opening, and an insertion portion extending into the opening and in contact with the inner surface of the flange, the stopper having a first CTE; and a filler member encased within the stopper and having a second CTE, the second CTE being lower than the first CTE.
Microfluidic network device
Microfluidic network device (2) configured to supply reagents to a biological tissue sampling device (1), comprising a plurality of microfluidic inlet channels (12) connected to respective sources of said reagents, at least one common outlet channel (22), and a plurality of valves (36) interconnecting an outlet end (14) of each of said plurality of inlet channels to said at least one common outlet channel.
Glass containers and sealing assemblies for maintaining seal integrity at low storage temperatures
A sealed pharmaceutical container includes a shoulder, a neck extending from the shoulder, and a flange extending from the neck. The flange includes an inclined sealing surface defining an opening in the sealed pharmaceutical container. The sealed pharmaceutical container also includes a sealing assembly including a stopper extending over the sealing surface of the flange and a cap securing the stopper to the flange. The stopper has a glass transition temperature (T.sub.g) that is greater than or equal to −70° C. and less than or equal to −45° C. The sealing assembly maintains a helium leakage rate of the sealed pharmaceutical container of less than or equal to 1.4×10.sup.−6 cm.sup.3/s as the sealed pharmaceutical container is cooled to a temperature of less than or equal to −45° C.
DEVICES AND METHODS FOR MESOFLUIDIC AND/OR MICROFLUIDIC PROCESSES
A cartridge can comprise a first elastomeric membrane and a second elastomeric membrane, and portions of the elastomeric membranes which are sealed to each other can circumscribe unsealed portions of the membranes. In a resting state, the unsealed portion of the first elastomeric membrane abuts or is proximate to the unsealed portion of the second elastomeric membrane. One or more reagents can be injected between the unsealed portions of the first and second elastomeric membranes to push the unsealed portions apart from each other in this region of the membranes. The unsealed portions can be sequentially pushed apart in downstream regions to form a channel between the elastomeric membranes. Positively displaced fluid pushes the unsealed membrane portions apart to a volume that conforms to the volume of the fluid to minimize or prevent dead volume in the channel and thus minimize or prevent air bubbles in the fluid.
